GUN-SIGHT.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed June 25, 1915. Serial No. 36,279.

To all whom it may concern Be it known that I, THOMAS E. KING, a citizen of the United States, residing at Frances, in the county of Pacific and State of lVashington, have invented certain new and useful Improvements in Gun-Sights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in gun sights and the principal object of the invention is to provide a sight which may be readily adjusted for use in gaging the distances of travel of the projectiles.

Another object of the invention is to provide a sight which is capable of being raised so that the gun may be used in damp weather without interference of the beads of water which might stand on the barrel during the sighting process.

A further object of the invention is to provide a sight which may be constructed of sheet metal and which depends for its adjustability on the friction of the metal against the walls of the guide.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a view of .a gun showing this improved forward sight applied thereto, illustrating the device used in the ordinary way and illustrating in dotted lines the gun used in wet weather. Fig. 2 is a view illustrating the means for lowering the barrel in case of an overshot. Fig. 3 is a detail per spective view of the block on which the sight is mounted. Fig. 4: is a sectional view through the block, and through the sight. Fig. 5 is a fragmentary detail perspective view of a rifle barrel showing a modified form of block and sight. Fig. 6 illustrates a globe sight constructed-in accordance with this invention. Fig. 7 is a longitudinal sectional view of a modified form of gun sight showing the screw adjustment, and Fig. 8 is a side View of Fig. 7.

Referring now to the drawings by characters of reference, the numeral 1 designates the gun barrel provided at its forward end with the usual dovetail groove 2, which extends transversely thereof and is designed to receive the dovetail extension on the sight.

My improved sight is designated generally by the numeral 3 and comprises the base block 4 having a dovetail extension 5 formed on the under side, which block is provided with the inclined upper face 6, which face in turn is formed with a longitudinally extending dovetail groove 7. Suitable screws 8 are threaded into the block at opposite ends of the groove 7 and in this groove 7 is slidably mounted the forward sight.

The sight hereinbefore referred to is designated generally by the numeral 9 and comprises a single strip of sheet metal bent to form the loop 10 provided with the silver or dull gold bead 11. The edges of the loop extend downwardly in parallel relation as at 12 and are provided with the outturned flanges 13 which are of the width to fit within the groove 7. A suitable strip of metal 14 is secured between the parallel portions 12 and is arranged to tend to force the free ends of the parallel portions outwardly so that the flanges 13 will frictionally engage the side walls of the groove 7 thereby holding the sight against accidental movement. The globe sight designated generally by the numeral 15 is likewise constructed of sheet metal forming the enlarged loop 16 and the parallel extensions 17, the lower end of which terminates in flanges 18. This globe sight is designed to be used in place of the sight 9 previously described if so desired.

In the modified form of the invention illustrated in Fig. 5, the gun barrel 19 is formed with the block 20, which in turn is provided with a longitudinally extending groove 21 at the inner extremity of which is a suitable opening 22. The sight 23 is slidable in the opening and is formed with an enlargement which fits within the opening 22 and this sight is provided with the dull gold bead 24 as clearly shown in the drawings.

In the modified form of gun sight illustrated in Figs. 7 and 8, it will be clearly seen that I have provided a sight which may be readily adjusted and which will remain in its adjusted position against accidental movement. In this modified form it will be seen that the body of the sight designated by the numeral 25 is provided with an enlarged bead 26 at its upper edge, which bead inclines upwardly and forwardly as in the sights previously described. The bead 26 is formed with a longitudinally extending bore 27 and the cap 28 is secured to the reduced end of the sight as shown. Extending through an opening formed in the cap is a screw 29 provided with a knurled head 30 and this screw extends through a screw threaded opening in the base of the sight member 31 to provide for ready adjustment of the sight member on the sight. In order that the sight member may be secured against movement in the sight there are provided the set screws which extend through the bead and when turned in place bind against the bottom of the sight member. thus preventing the same from moving accidentally or upon turning the screws.

From the foregoing it will be apparent that in use the ordinary sight is removed from the gun or rifle barrel and the block & slipped in place. Either the globe sight or the ordinary sight is then placed in the dovetail groove 7 and the same is then ready for use. If a person finds upon using the device that they are overshooting the barrel may be lowered by moving the sight forward, thereby bringing the projectile down nearer in line. Should the barrel become wet and sighting down the same become difficult, the sight may be raised and the rear sight brought to the proper position with relation thereto, thus raising the line of sight to a point above the beads of water which might stand on the barrel, thereby insuring accuracy in shooting.

Vhile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claims.

Vhat is claimed is 1. The combination with a gun including a barrel, of a block at the forward end of the barrel, the upper face of the block being inclined upwardly and forwardly, said face having a dovetail groove extending throughout its entire length, a sight slidable in the groove and means to limit the movement of the sight to prevent the same from being removed from the block.

The combination with a gun, a block at the forward end of the gun, the block being formed with an upwardly and forwardly inclined upper face, said block also having a dovetail groove extending longitudinally of the inclined face, and a sight slidably mounted in the groove.

3. The combination with a gun having a barrel, of a block carried by the forward end of the gun barrel, an upwardly and forwardly inclined face formed on the upper side of the block, said face being provided with a longitudinally extending dovetail groove, a sheet metal sight including a bead, a web and flanges extending laterally from the web, said flanges being slidable in the groove, and means to force the flanges outwardly and into frictional engagement with the side walls of the groove.

In testimony whereof I afiix my signa ture in presence of two witnesses.
